Page 12: Installation
Seanet SCU v5 3. Installation The Seanet SCU (v5) should be carefully removed from its transit case and checked to see that the control unit is undamaged. The unit may be inverted to check for any parts that may have been loosened during transit. If so, remove the unit cover and investigate further. The unit should be firmly mounted in a clean dry installation such as a rack system. -
Page 13: Communication Configuration
Installation Seanet SCU v5 3.2. Communication Configuration Fitted inside the SCU, located at the front panel, is the SCUv5 Main Board. This is a multi- purpose board that houses the bulk of the circuitry from the superseded AIF PCB. This includes the ARCNET interface, for communications with the subsea sensor heads, and the RAT interface. - Page 14 Installation Seanet SCU v5 Use with Serial Devices The SCU is installed with four DE-9 ports on the rear panel for use with serial communications. These ports can be configured for different standards and for survey data output ports to a data logger or as ports where Tritech International Ltd or other 3rd party sensors/devices can be connected.

Seanet SCU v5 Appendix B. SCUv5 Communications Setup There is no AIF card inside the V5 Seanet SCU, in its place is the V5 Main Board. The Main Board provides 4 Serial Ports A,B,C,D which can be configured to RS232, RS485 or RS422. These are available on separate 9 pin D-type connectors In addition to this the Main Board feeds a 15 pin D-type connector which has the same pinouts as the 15D connector fitted to the AIF card on earlier SCU models. - Page 25 SCUv5 Communications Setup Seanet SCU v5 Tritech DA-15 Connector Connector ARCNET A ARCNET B (see note) (see note) Tritech 6-pin connector ARCNET A SCU DA-15 female connector ARCNET B nc = not connected Note Power will need to be supplied to the sonar head through pin 3 (for example 24V DC supply for a SeaKing) and pin 4 (0V ground) of the Tritech connector - the ARCNET port will not be able to supply this power and a suitable external source should be used.
